more than twice as fast as the previous Operating System Manager (OSM) download
method. This chapter describes the recommended method for enabling CVT
downloads in a network with BFS QAMs that are each operating at the same
(overlapping) or at different (non-overlapping) frequencies. If you are familiar with
the OSM method, keep in mind that the CVT method works a little differently. For
example, the CVT method does not use the carousels created and managed by BFS.
Instead, the OSM process creates and manages its own carousel for the delivery of
images identified in the CVT table. In addition, specific to a distributed BFS
configuration, the secondary QAMs use continuous feed (CF) sessions to distribute
the BFS and OSM data to the secondary QAMs.
Configuring the CVT download method can take up to two hours to complete.
